1.7.2 Maximum Query Response Time

For every inclusion report received by the querier, the particular interface entry is added in the IGMP
group table for that particular group. A group membership timeout is then started for each
group/interface entry in the IGMP group table. The query response interval is used to calculate the
group membership timeout.
Group membership timeout = (robustness value * query interval) + max query response interval.
Once a query is received by the hosts, they should respond with IGMP reports within the max query
response time. The querier deletes the hosts' interface entry from the IGMP group table if no reports are
received from the host by the time the group membership timeout is reached.
The default query-max-response time is 100 seconds.
Supermicro switches provide flexibility for users to configure different query-max-response times on
different interfaces.
Follow the steps below to change the query-max-response on any interface.
Step Command
Step 1 configure terminal
Step 2 interface <interface-type> <interface-id>
or
interface range <interface-type> <interface-id> ....

mode.
interface-type – may be any of the
following:
gigabit ethernet – gi
extreme-ethernet – ex
qx-ethernet – qx
vlan
interface-id is in slot/port format for all
physical interfaces. It may be the VLAN
identifier for VLAN interfaces.
To configure multiple interfaces, use
the "interface range ..." command. To
provide a range use a hypen (-)
between the start and end interface
numbers. E.g.: int range gi 0/1-10
To provide multiple interfaces or
ranges, separate with a comma (,).
E.g.: int range gi 0/1-10, gi 0/20
If multiple interfaces are provided, the
next step will enable IGMP on all these
